' the above product resulting: product from excess of formaldehyder r i. As a gypical example of the proportions temploye .incarrying out my process, I first add twenty(20) pounds of iodin, either as to a solutionof fifty (50) pounds of casein. Thereafter I place in a suitable vessel fifty (50) pounds of and, to it. add eight (8) pints of a forty per-cent. (40%) solu tion of formaldehyde, allowing the same to stand for two or three days, after which the precipitate collected on a filter, washed, and dried. Theproduct resulting from the above described rocess is an iodoanhydro-methylene protei' containing about twenty per-cent. (20%) of iodin in organic combination.

about 20% of iodin in organic combination.

Not all; of a this iodin is combined in the 'same way, for part of it can readily by treatment with sodium thiosulfate soluti0n.- The. remaining part, how- 7 ever, is combined veryfirmly and can be lib-i the action of concentrated or any, other proteid is the equivalent of and maybe subst1tuted for the casein 1n carrying be split off very out myfinvention, and that the proportions jn'oted' may be considerably varied departing from said invention. I I Iclaim;-- 1. The process of preparing iodo-anhydromethylene -proteid which consists in acting on a. proteid with roduct of such re-action to the-actionof ormaldehyde; and thereafter separating out the-desired product.

'2. The methylene proteid, which consists in acting (50) :pounds' of a proteid with twenty (20) pounds of iodin; treating fifty -(50) pounds with eight (8)" ints of a forty per-cent.
